Iwas going on my first really important business trip. my flight (1)_ (to schedule) for 9 am and i had got up extra early to ensure that i got to the airport on time. while i (2)_ (to walk up) to the chek-in desk, i took a quick look in my briefcase to make sure that i had my laptop and all the papers i (too need) (3) for my presentation/ everything was there/ i gave the girl at the desk my ticked and she (to hand)(4) me my boarding card.
